My 2020 Silverado HD truck requires a replacement wiring harness and DEF tank and is basically inoperable. This is a known issue for GM and spans multiple model years.GM continued to produce throughout multiple model years knowing that owners may be stranded and unable to use these vehicles because of the defective parts. Hardships for owners would include loss of income and exposure to various dangerous conditions. The DEF tank has a heater system that can get exposed to the DEF fluid because of a poor design and poor manufacturing standards resulting in short circuit. GM will replace the wiring harness and combination tank/heater assembly under warranty. The parts are supposedly on NATIONAL BACK ORDER, yet GM continues to manufacture and ship new 2022 models with the required parts needed for repairs. GM will not provide alternate transportation. Supposedly in excess of ten thousand trucks are affected. Warm climate owners and warm temperatures may affect this issue positively. GM has no policy for a timely response to this issue. Trucks will become unsafe to operate when the electronic controls limit the truck speed to 5 mph or less. An operator may become stranded and exposed to dangerous highway conditions if stranded with this issue.

The DEF heater/tank shorted out. The DEF system has thrown a code 3 times in the little over a year I’ve owned the truck. This final time I was told that the tank needs to be replaced. The truck has now been in the shop for 2 months and there is still no ship date on the replacement tank. The tanks are on a national back order. From what I understand there are about 9,000 people waiting for this DEF tank countrywide. I now have a $60k work truck that I am paying for but cannot use with no reasonable end in sight.

Service DEF message in truck that will soon result in reduced speed. Local and purchasing dealers both stated a new DEF tank is needed. A tank is not available and is on back order.

DEF tank heater short causes wiring harness to melt and fault on diesel trucks, enabling limp mode. Limp mode is dangerous when hauling trailers over long distances. Faulty part is on 6 month backorder. No reparations from GM.

The contact owns a 2020 Chevrolet Silverado 2500 HD. The contact stated that while driving at 50 MPH, a warning alarm engaged and advised that there was an emission system issue and the vehicle needed to be serviced within 160 miles. The transmission warning light illuminated. The contact stated that she parked at some point to run an errand and upon restarting the vehicle, a death issue system alarm engaged indicating that the vehicle needed to be repaired within 90 miles. The vehicle was taken to the local dealer where the failure was diagnosed as a dead issue and one of the pins on the wiring harness had burnt and was starting to melt. The local dealer informed the contact that the death tank and wiring harness needed to be replaced; however, the parts for the repair were not available the vehicle was not drivable. The vehicle was not repaired. The manufacturer was notified of the failure and advised the contact the parts for the repair were not available. The vehicle was not repaired. The failure mileage was approximately 20,000.

While plowing, my ABS brake light came on along with a warning that the ESC was disabled and a trailer brake system warning.. This appears to have been a recall for 2020 1500's but I have a 2500. It would appear the recall needs to be expanded.

Truck on its own Shift from Park to Drive on its own while at idle. Summary: My 2020 Silverado 2500HD was in the driveway idling in Park. The vehicle was empty and I was checking the garage for screws from a project I had just completed and I wanted to make sure they were all picked up before I parked the truck in the garage so that I did not get a flat tire. After looking for screws and assuring myself everything was cleaned I proceeded into the third bay of our garage and right behind me by an inch the truck proceeded into the garage at a good rate of speed and crashed into the house. I quickly ran through the third bay and to the vehicle as it was still wanting to proceed into the house. I quickly shifted it into Reverse from Drive backed up about 2 to 3 feet and placed the truck back into Park again and placed the emergency brake on and shut the truck off...

The brake pads which were installed from the factory are known by GM as being defective. This was acknowledged when technical bulletin 20-NA-020 was released. The brake pads were know to contain low scorch friction material which can lead to premature wear. When this was discovered, GM began installing new pads which have a high scorch friction material and feature a new lining shim on the backing plate. GM failed to notify their customers of this problem. GM has done this deliberately since once the vehicle reaches over 7,500 miles, the pads are no longer under warranty. I discovered my vehicle was effected from this due to increasingly hearing a high pitch screeching sound coming from the vehicle. After immediately noticing the issue, I scheduled a service appointment and conducted my own research of this issue. This is when I discovered the technical bulletin. Due to my vehicle having over 7,500 miles, I was advised the cost for replacement is my responsibility. The cost for replacement including parts and labor from Chevrolet is approximately $750-$800. This issue is a direct safety concern and a known problem which GM failed to notify their customers of. GM deliberately withheld this information to shift the cost burden of replacement to customers beyond the 7,500 mile warranty period.
